A silly grin

I have been riding my bike around today with such a silly grin on my face.  I don't think this drawing is very good except that it captures the silly grin exactly!  My new bike is a joy to ride and I couldn't stop smiling about it.

I feel rather tired tonight and I don't know whether that is a consequence of the yoga class, the heat or just that I have been busy - although I don't think I have been that busy in that I don't seem to have done very much.  The things I have done, however, have required a lot of my energy and attention either because I was focusing on a person or because I was talking about things in Buddha Garden that required a lot of thought.
